A satellite dish can receive signals from multiple satellites by using one LNB for each satellite. This configuration has advantages and disadvantages. The main advantage over a motorized dish is that you can change channels quickly, but the non-center LNBs will receive lower quality signal.

The multiple LNB bracket must keep a constant focal distance and must follow the inverted reflection of Clarke orbit. The focal distance depends on antenna and orbit reflection depends on location. The distance between LNBs is proportional with dish diameter. Later I will show how these parameters affect the LNB bracket shape and size.
